Abstract. Spontaneously emergent ripples on fused silica surface under homogeneous oblique incidence of Ar ions accelerated up to 4.25 keV are reintroduced together with increasing recent related studies in theories and experiments for variety of combinations of ions and materials. The features of the ripple formation are discussed with an interest in similarity with ripples formed on sand by the wind.
